You need to read the post at the top of the SSRs For Sale Forum that explains the rules. ( I don't make the rules but I do have to enforce them)
Then you can explain what you have as mentioned above. There are some ways to get a few more posts since you must have 15 posts in order to use PMs since you are not a Supporting Memberr.
Good luck with your sale. hHere are probably several around who will be willing to post pictures if you have them
